Specification of Letters Patent.

T0 all whom it may concern.'

Be it known that I, FREDERICK W. Frml LERToN, a citizen of the UnitedStates, residing at St. Paul, in the county of Ramsey and State ofMinnesota, have invented a new and useful Improvement inNewspaper-Conveyers, of which the following is'a specification; Myinvention relates to improvements in newspaper conveyers and 'moreparticularly to a conveyer, which is adapted for use in connection withthe modern printing press.

An object of my invention is to provide a conveyer for newspapers andother printed papers, which will receive the papers from the press andtransmit them by any convenient route to a delivery table where thepapers are usually stacked and counted.

My conveyer isiparticularly adapted to the transmission of folded paperswithout smearing the fresh printers ink through contact with the beltsand without creasing or breaking the folded papers where the conveyerchanges direction. It also reduces wear between the papers and belts andis practically noiseless My improvement also vcauses a pair of saidbelts to tightly and evenly grip and accommodate printed papers ofdifferent sizes and weights with substantially uniform pressure wherebythe papers are prevented yfrom creeping and becoming disarranged ordamaged. The Vconstruction also admits of quickly repairing broken ordamaged parts with ease in case of accident.

The mechanism with which the conveyer is operated is also simple inconstruction and 'l light in operation being applied in use aroundsha'rp corners and through ceilings and walls with little difficulty.

In the accompanying drawing forming part of this specification, Figure 1is a diagrammatic view, showing the application of my invention toseveral of the dierent conditions of a newspaper-'conveying system; Fig.2 is an end view of a detail Yof the. conveyer system; Fig. 3 is a planof adetail of the conveyer system; Fig. 4 is a plan of a portion of oneofrthe belts, and Fig. 5'

is a side view of one of the sets'of pulleys orsheaves.4

In Fig.V 1 of the above drawing is illustrated my improved conveyerhaving a newsv paper receiver A', a downward to horizontal change indirection B, a horizontal to a The conveyer is adapted to be connectedtoa printing press not illustrated to operate by any convenient source ofpowerin synchronism with the delivery mechanism of the press. As thepapers E pass through the conveyer, which may be' of any length desiredand fitted with any of the changes of direction shown, to bring thepapers to the required delivery point, they are passed on to the table Dand stacked and can be removed from the table as desired.

A vprimary feature of my invention consists iniarranging carrier beltscomposed of substantially endless helical spring wire strands 44, (seeFig. 4), held under tension so that the adjacent sides or'surfaces ofcooperating belts are adapted to grip papers between said sides andconvey them evenly from one point to another without the papers becomingdisarranged or slipping and the freshly printed surfaces smudgedf Anembodiment of this idea and other features of novel construction areincorporated inthe apparatus set forth in the following description.

The receiver `A consists of a plurality of sheaves 3 being mounted atsubstantiallyl equal distances apart upon a shaft 5 and the rammed Maya, i915.

belts 2 running over sheaves 3 and 4, the

sheaves 4 mounted in the same manner en the shaft 6, all of said sheavesbeing of equal diameter, whereby all of the belts 2 are adapted to liewith their upper and. lower sides respectively in approxim atelyladjacent horizontal planes. The shafts 5 and 6 are journaled 'uponsuitable supports such as 7, which are mounted upon the floor or ceiling8 of the building of a structure containing the conveyer system, theshaft being arranged above an opening 9 in said -loor or ceiling, sothat the downward eXtension of vthe conveyer may. pass freely `throughvsaid opening. The downward eX- j 100 tension F of the conveyer iscomposed of a group of belts similar to belts 2 'passing over sheaves10, (see Fig. 5), on the sha-'ft 6 lying vadjacent to the sheaves 4, andover sheaves 11.011' a shaft 12, which is supported below the ceiling 8.The sheaves 4 andlO are of the/same diameter and the beltsl travel 'atthe same surface speed as the belts 2 serving to assist in conveying thepapers from a horizontal-direction downwardly on to another group ofhorizontal belts 14. 'The shaft 12 is of similarV construction to theshaft 6, being providedvith sheaves similar to 4 and lQffgr'thedownwardly extending belts 13' latter alsop'as'sing around sheaves 15 ona shaft 16 at the'turn C, the belts 14 passing through an opening 17 inthe upper portion of a partition such as 18. After passingthrought-"said opening and around the sheavesv onf-,the shaft 16, thepapers are assisted in being carried downwardly by downwardlyextendingbelts 19 passing over one of the sets of sheaves on the shaft16, which is similar to the construction illus- I trated in Fig. 5, andover another set of sheaves 20, carried by the shaft 21. The papers uponreaching the lower end of the belt 19 are turned by alaterally'extending set of belts 22 passing around sheaves 23 on a shaft24, and sheaves on the shaft 21 which are similar to those illustratedin Fig. 5, whereupon the papers are deliveredV upon the table D, whichis in the form of la frame having transverse shafts 25 journaled in itsends and carrying sets of sheaves 26 and 27 aroundwhich a set of belts28 are passed. The papers are deposited upon /the belts 28 and stackedin the usual manner by moving the belts with their upper sides away fromthe delivery end of the conveyer. p

Arranged above the receiving belts 2 is an auxiliary set of belts 30,traveling over sheaves 31 on the shaft 32 and over sheaves 33 onthe'shaft 34, the lower sides of said belts being adapted to coperatewith the upper sidesoof the belts 2 to assist in conveying the papers ina forward direction. Situated adjacent the sides of the belts 13, whichconvey the papers is another auxiliary set of belts 35 having sideswhich also 'coperate with the adjacent sides of the belts 13 to assistin conveying the papers forwardly in a downward direction upon `theupper sides of the belts 14. The belts 35 pass around sheaves 36 `on ashaft 37, and a set of sheaves similar to the sheaves 10, mounted uponthe shaft 34, said shaft 34 and the sheaves which it carries beingsimilar in construction to that illustrated in Fig. 5. At the pointwhere the papers turn from the 'receiving belts 2linto a downwarddirection and from the belts 13 into a horizontal direction, guides 40are positioned in the form of guide arms, which are mounted` upon shaftssuch as 41 and urged against thepapers by springs42, thus assisting thepapers in turning evenly without becoming disarranged or damaged. Guides43 are similarly placed at the turn from a 'horizontal direction, inwhich the belts 14 travel, into adownward Yiirection assumed by thebeltslf).

he horizontal belts 14, the

`All ofthe belts lemployed the conveyer 'are made of helical spring wire44, whereby vthe sidesor surfaces .of the` blts' areheld under tensionto prevent'slippingupon'the pulleys and causing thea'djacent' sides ofthe beltspvhich coperate tohold the papers ,betweenwth'emand carry theApapers for wardly in a positive ma'nner without creasing and becomingdisarranged or the fresh printers ink smudged.

All of the sheaves are driven by link belts and sprockets 45 and' 46connected 'with their shafts so that the helical belts are positivelydriven wherever-they pass over the sheaves, whereby the belts arerelieved from all driving strain and sagging and are caused to moreevenly grip the papers without permitting the papers to collect inbunches. rlhe auxiliary belts are driven by trains of gears 47 land 48con` nected with shafts 6 and 34 and 16 and 49, i

the use of these offsetting sheaves but where the stretches are long andup and down and the helical belts small in diameter and comparativelyweak. Said sheaves are desirable.

Ihe auxiliarybelts 30 run from a high point t0 a low point of travel ascompared with the horizontal runs for the purposes of gradually guidingthe papers into the bite of the belts and coperating with the guides 40toturn the papers around a corner.

The delivery table D has motion transmitted to its carrier belts 28 byan eccentric 5l on the shaft 21 and a pawl 52 carried by said eccentricand coperating with the teeth of a ratchetvwheel 53 secured uponthe 22.In this manner a step by step motion at a relatively slower advancingspeed than that of the main carrier beltsis imparted to thereceivingbelt, causingl the papers to be stacked in `convenient,position to bev counted and handled'by the operators. Thelvai'iou's "'rev oluble elements and guides are suit'- ably journaled or,l supportedby brackets such as 7 and '54, or by thev walls, ceilings and floorscofa building, or by any other Suitable'Supports.

The conyeyer admits of application to the various structures andconditions surrounding printing presses and while the appashaft 25nearest the delivery end of the belt isos ratus shown illustrates onemode of application wherein the papers are carried from a high to a lowpoint, it is obvious that the invention is applicable with equaleiciency where the transmission is from a low to a high point. Y

In accordance with the patent statutes I have described the principlesof operation of my invention-together with the apparatus which I nowconsider to represent the best embodiment thereof but I desire to haveit understood that the construction shown is only illustrative and thatthe in vention can be carried out by other means and applied to usesother than those above set forth within the scope of the followingclaims.
